Go look up a reference that proves me wrong, showing the spitfire had positive static stability.


I don't claim the spitfire had dynamic stability, I say it is neutral, which simply means it does not try to return to it's original condition, as opposed to dynamic instability where the aircraft would increase it's amplitude of error, enough proof against dynamic instability is the fact the aircraft was not notorious for PIO (pilot induced oscilation) incidents, neutral stability is a desireable quality for an aircraft built purpousely to be agile/manouverable......seems Mitchel designed it just right.

I attached a scan from Kermodes 'Mechanics of flight' and have highlighted in red the 3 conditions, perhaps there are differences in our understanding but I feel it explains where I'm coming from.
